Abstract
This paper describes an investigation into the effective length of columns subjected to axial loads, for the various conditions encountered during the construction of buildings using the lift-slab method. Many designers of lift-slab construction have assumed an effective length factor, K, for all conditions, equal to 2.0, and have believed that this assumption is reasonable or conservative. The investigation shows that for many conditions a K value equal to 2.0 is reasonable or conservative; however, the investigation also shows conditions where effective length factors greater than 2.0 should be used, and where effective lengths much lower than 2.0 could be used.
